| Abstract: | Research was completed using the position observation method on the poplar plantation in the beach of south and west Dongting Lake also quantitative research on the groundwater level of the beach and the moisture content of soil was done to determine the relationship of the changing regularity of Oncamelania hupensis with poplar plantation. The adventitious effect of environmental factors and the growth and decline regularity of Oncamelania hupensis in poplar plantations were measured. The effect of the retarded growth of Oncamelania hupensis by the poplar plantation ecological system was measured and the safety significance of beach poplar was shown in the article. |
